3 Wheels Good - 4 Wheels Bad

I would dearly like to get into the game of designing my own motor vehicle.

But there are enough hours in the day only for following Jesus, sleeping, providing for the family at the moment. But here is the - would be - approach.

a) Find a 3D cad package. Free would be best. Cheap ok.

- a  few candidates.

b) Find a front end donor dual wishbone + drive suspension system from a small sports car who has been horribly rear-ended.

c) Find a rear single swingarm and adapter plate to a car wheel. (VFR?)

d) Draw a chassis design to accomodate the chosen suspension system. 

e) Choose a compact engine/gearbox that fits! VW 1600cc or MotoGuzzi v twin engine with a VW gearbox.

f) Accomodate engine mounts for chassis. 

g) Do some FEA analysis. - get some engineering knowhow to see if my chassis is any good.

h) save pennies.. lots of them. 

h) Get welding!

i) Build control arms for steering / drive. 

j) Fibreglass chassis moulding..

Plan B.
A blackjack zero!
